Abstract

A liquid-column flue gas desulfurizer capable of flexibly coping with the change of conditions such as desulfurization performance, field adjustment, and so on, by which the increase of cost and construction time can be minimized. In the liquid-column flue gas desulfurizer for performing desulfurization by bringing absorbing liquid which is jetted upward from a liquid column nozzle (20) and falls in a desulfurization tower and combustion exhaust gas which rises from the bottom of the desulfurization tower into gas-liquid contact with each other, an outlet chip (30) having a different jet flow rate or jet pattern of the absorbing liquid is removably attached to the tip of the liquid column nozzle (20). By attaching a liquid column dispersing mechanism to the tip of the liquid column nozzle, the dispersion of a liquid column can be accelerated and the area of the absorbing liquid brought into contact with the combustion exhaust gas can be increased. Consequently, the desulfurization efficiency can be improved and the size of the desulfurization tower can be reduced, which is very effective in reducing the installation space and cost of the device.
